Abstract

Ein Drehzahlregelkreis, bei dem die zum Vergleich mit den Sollwerten benötigten Istwerte von einer Vorrichtung abgenommen werden, unterliegt fertigungsbedingten Toleranzen. Ein automatischer Ausgleich dieser sogenannten Teilungsfehler erfolgt dadurch, daß den einzelnen Tachoim­ pulsen eigene Führungsgrößen, zu deren Anspeicherung ein Speicher vorgesehen ist, zugeordnet werden, und daß diese Führungsgrößen in Abhängigkeit von der jeweils ermittelten Regeldifferenz in einem Hilfsregler ständig korrigiert und ans­ telle der alten Werte im Speicher abgelegt werden. Eine solche Vorregelung, die die relativen Fehler zwischen den benachbarten Tachoimpulsen erfaßt, ermöglicht eine exakte Einstellung der gewünschten Drehzahl, wie sie beispielsweise in Videorecordern zum Erhalt eines guten Bildes nötig ist. A speed control loop in which the for comparison with the actual values required by a device be removed, is subject to production-related Tolerances. An automatic compensation of these so-called Division error occurs because the individual speedometer pulse their own command variables to store them Memory is provided to be allocated and that this Reference variables depending on the determined Control difference in an auxiliary controller constantly corrected and ans the old values are stored in the memory. A such pre-regulation that the relative errors between the adjacent tachometer pulses detected, allows an exact Setting the desired speed, such as in video recorders to get a good picture.
